Abstract
A lock device is provided for locking an accessory-grip to a camera body. A lock lever is movably supported by a housing. The lock lever is moved and can be stopped at a lock position, a partial release position, and a complete release position. First and second connecting members are movably supported by the housing, and can be displaced in association with the lock lever. When the lock lever is positioned at the lock position, the first and second connecting members are engaged with the camera body. When the lock lever is positioned at the partial release position, the first connecting member is released from the camera body and the second connecting member maintains the engaged state.
